I am a machinist. We use shim stock all day long. The
thinnest shim we have been able to find is .0005 which
is half a thousandth or five ten thousandths. We
(Boeing) have not been able to find shim in .0001. But
then, it woulkd be so weak it would tear when you
drilled it. .001 works teriffic. I have used up to
.002 with success. It is best if you drill a smaller
hole with a needle then knock the burr off the other
side with sandpaper, drill larger, deburr and go to
final size. The thinned the shim material is at the
edge of the hole the less diffraction problems you
will have.
